An ice skater starts with a velocity of 2.25 m/s in a 50.0 direction. after 8.33 s, she is moving 4.65 m/s in a 120 direction. what is the x-component of her acceleration?
find the magnitude and

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Increasing the pressure on one spot of a fluid will increase the pressure everywhere else in the fluid a. pascals principal b. archimedes' principal c. bernoulli's principal
